TECHNICAL FIELD

The present invention relates to door for a cooking food oven.

BACKGROUND

It is known a cooking oven comprising a cooking compartment and onedoor. The door includes a first and a second glass panel.

In the configuration of closed door, the first glass panel delimits thecooking compartment while the second glass panel is directly accessiblefrom the outside. The first and second panels are placed side by sideand parallel in such a way as to create at least a gap for the passageof fluid flow. This arrangement helps to reduce the risk that a user maybe burnt by touching the second panel of the door and at the same timeallows the use of transparent glass, that allow a user to look insidethe cooking compartment.

In order to carry out cleaning and maintenance interventions, at leastthe first glass panel is removable.

In this regard, this oven comprises locking means provided withprotrusions which may be rotated between a first position in which theyhold the first panel and a second position in which release the firstpanel. To move said protrusion from the first to the second position orvice versa, it is necessary to rotate a pivot which is integral to theprotrusion. In this regard a screwdriver or another tool may be used torotate a slot properly formed in the pivot.

A drawback of such a constructive solution is due to the fact that, inorder to easily move the protrusion from the first to the secondposition the user must open the door completely and also must usehelping tools.

SUMMARY

In this context, the technical object at the base of the presentinvention is to propose an oven for cooking food that overcomes thedrawbacks of the prior art mentioned above.

In particular, it is the aim of the present invention to provide an ovenfor cooking food that allows an easier mounting and removing of somecomponents of the oven (typically of the glass panel closest to thecooking compartment).

The specified technical object and the specified aims are substantiallyachieved by an oven for cooking food, comprising the technicalcharacteristics described in one or more of the attached claims.

DETAILED DESCRIPTION

In the attached figures, with the number 1 it was indicated an oven forcooking food. The cooking oven 1 comprises an enclosure 20 whichidentifies a cooking compartment 2. The enclosure 20 comprises a bottombase, a top opposite to the base, two opposing side walls and a backwall. The cooking oven 1 also comprises a door 3, which is movablebetween an open position in which it permits access to the compartment2, and a closed position in which it contributes to delimiting thecompartment 2. The door 3 at least in the closed position extendssubstantially vertically. The door 3 in the closing position is oppositeto said back wall.

The door 3 comprises: a first panel 4 which, in the closingconfiguration of the door 3 contributes to delimiting said compartment2; a second panel 5 which, in the closed configuration of the door 3 isat greater distance from said compartment 2 than the first panel 4.Typically the second panel 5 is directly accessible from the outside ofthe oven 1 even with the door 3 closed.

Conveniently, the first and the second panel 4 and 5 are substantiallyparallel. In the embodiment both the first and the second panel 4, 5 areat least partially transparent. Typically they are made of glass. Inthis way even with the door 3 closed they allow to look inside thecompartment 2.

Between the first and second panel 4, 5 is usually present a gap 50.This gap 50 preferably defines a channel for the passage of a coolingflow. In this way the temperature reached by the second panel 5 duringthe operation of the oven 1 is reduced (thus decreasing the risk ofburns to the user that could accidentally touch the second panel 5). Thegap 50 could be bounded directly from the first and second panel 4, 5 ormore in general could be interposed between them.

Conveniently between the first and second panel 4, 5 could be interposedat least one intermediate panel 51. The eventual intermediate panel 51helps to reduce the temperature of the second panel 5 during theoperation of the oven 1.

Conveniently the door 3 comprises a first and a second body 6, 7 forsupporting the first and second panel 4, 5. The first and the secondbodies 6 and 7 can perform the action to support the first and thesecond panel 4, 5 directly or indirectly (through the interposition ofintermediate elements). In any case, the first and the second bodies 6,7 support the weight of the first and second panel 4, 5. The first andsecond bodies 6, 7 have a preponderant longitudinal extension.

The first and second bodies 6 and 7, therefore, extend each one alongits own predominant extensive direction. Conveniently, the first and thesecond bodies 6, 7 are parallel. In the attached figures, the first andthe second bodies 6, 7 define uprights. First and second bodies 6, 7 canbe a single body or an assembly of more elements. The first and secondbodies 6, 7 are interposed between the first and the second panel 4, 5.

The first and second body 6, 7 are hinged to said enclosure 20.Preferably the second panel 5 is connected to first and second body 6, 7by adhesive means. The door 3 also comprises a profile 8, which ismovable between a first position in which it contributes to retainingthe first panel 4 in position and a second position in which it permitsthe removal of the first panel 4 from the door 3. Therefore, during thenormal operation of the oven 1 the profile 8 is in the first positionwhereas it is placed in the second position to allow the removal of thefirst panel 4 in order to support cleaning or replacement. Profile 8 isplaced in second position also in order to support cleaning orreplacement of portions of the door 3, otherwise not accessible by anoperator.

At least in the first position said profile 8 extends preponderantlyalong a side of said first panel 4 (along this extension profile 8preferably alternates areas 810 where it is in contact with the firstpanel 4 and areas 811 where it is not in contact with the first panel4).

At least in the first position, the profile 8 extends in a directionthat is transverse to the preponderant extension of the first and secondbodies 6, 7. Typically the first panel 4 has a rectangular shape.Advantageously, but not necessarily, the profile 8 extends along thelongest side of said rectangle. Typically, the profile 8 extends alongat least a part of the upper side of said rectangle (in order toestimate which is the upper side, the door 3 must be considered in theclosing position).

The door 3 further comprises connection means 9 of the push-push typefor connecting the profile 8 to remaining portions of the door 3(remaining portions of the door means at least a part of the door 3distinct from profile 8).

The push-push type connection means 9 as such are well known.

The push-push type connection means 9 comprise a first push-pushconnector 91 in turn comprising a first element 911 incorporated in orconstrained to the profile 8 and a second element 912 constrained to thefirst body 6. In the embodiment the first element 911 is in a singlebody with profile 8.

In a first operating mode the first and second elements 911, 912 arereciprocally coupled and in a second operating mode the first and secondelement 911, 912 are uncoupled.

The first and second element 911, 912 are one a male component and theother a female component. The first push-push connector 91 has twostable positions which correspond to the first and the second operatingmode. To move from the second operating mode to the first operatingmode, the male component is introduced making a pressure in the femalecomponent along an insertion direction, up to the reaching of one ofsaid two stable positions. To move from the first to the secondoperating mode, it is performed a pressure according to said insertiondirection that unlocks said male component from said female component.

The push-push type connection means 9 comprise a second push-pushconnector 92. The second push-push connector 92 comprises a firstcomponent 921 incorporated in or constrained to profile 8 and a secondcomponent 922 constrained to the first body 6. In this regard in theembodiment the first and the second push-push connector 91, 92 arearranged symmetrically to a vertical plane interposed between them andorthogonal to the first panel 4.

Conveniently, the operation of the first and second connector 91, 92 issubstantially the same. In particular what has been described withreference to the first and second element 911, 912 may be repeatedrespectively for the first and the second component 921, 922. The user,by acting with only one hand on the profile 8 can activatesimultaneously both the first and the second connector 91, 92.

In the first operating mode the first and second component 921, 922 aremutually coupled and in said second operating mode the first and secondcomponents 921, 922 are uncoupled. In this way a pressure on the profile8 directed toward the gap 50 corresponds to a locking of the profile 8,a subsequent pressure on profile 8 directed toward the gap 50corresponds to an unlocking of profile 8.

By way of example, but not limiting example the first and the secondpush-push connector 91, 92 can be push-push connectors PR261.S01marketed by the company Illinois Tool Works Inc.

Advantageously the oven 1 comprises: a first hinge 60 located at a firstend 61 of the first body 6; a second hinge 70 located at a first end 71of the second body 7. The first and second hinges 70 permit the movement(to be tipped) of the door 3 relative to the remaining parts of the oven1 (in particular relative to the enclosure 20). This allows the openingand closing of the door 3.

In the illustrative embodiment shown in the attached figures, the door 3rotates around a horizontal axis. In an alternative embodiment notshown, the door 3 could; however, rotate around a vertical axis (in thiscase, the first and second bodies 6 and 7 would extend horizontally).Profile 8 in the first position connects a second end 62 of the firstbody 6 and a second end 72 of the second body 7.

The first body 6 comprises a housing cavity 63 of the second element 912of the first connector 91. Similarly, the second body 7 comprises ahousing cavity of the second component 922.

The profile 8 comprises an edge 80 for holding the first panel 4. Insaid first position this edge 80 prevents the first panel 4 to move awayfrom the second panel 5. The retaining edge 80 performs a retainingaction on an upper portion 40 of the first panel 4, said upper portion40 being considered with reference to the door 3 in the closingposition.

Referring to the closing position of the door 3, upper portion of thefirst sheet 4 refers to a part of the first panel 4 extending verticallyto 10 centimeters.

Conveniently the door 3 comprises means 73 for retaining the first panel4 operating on a lower portion of said first panel 4, said lower portionbeing considered with reference to a closing position of the door 3. Themeans 73 for retaining the first panel 4 comprise, for example, a firstbracket 74 which extends projecting from the first body 6.

In the closing position of the door 3, the first bracket 74 comprises afirst part which extends away from the first body 6 and a second partthat extends upward from the first part. The first bracket 74 thereforehas an “L” structure.

The means 73 for retaining the first panel 4 comprise conveniently asecond bracket 75 which extends to projecting from the second body 7.

In the closing position of the door 3 the second bracket 75 comprises afirst part which extends away from the second body 7 and a second partthat extends upward from the first section of the second bracket. Thesecond bracket 75 therefore has an “L” structure.

Profile 8 comprises a first portion 81 that in the first position andwith the door 3 in the closing position occludes the upper side, atleast in part, a space interposed between the first and the secondpanels 4, 5.

In particular, the first portion 81 at least partially occludes said gap50. The first portion 81 may comprise one or more openings that allowthe passage of the cooling flow passing through said gap 50.Conveniently, the first element 911 and the first component 921 extendprojecting from said first portion 81. With reference to the attachedfigures, when the door 3 is in the closing position, advantageously, thefirst element 911 and the first component 921 extend downwards from thefirst portion 81. Conveniently in the closing position of the door 3,the first and the second bodies 6, 7 extend vertically. The first andsecond bodies 6, 7 can have a tubular shape and respectively canaccommodate within them said second element 912 and said secondcomponent 922.

In the exemplified embodiment in FIGS. 2-4, profile 8 is removable fromthe door 3. In particular, once that push-push type connection means 9were disconnected, the profile 8 can be completely removed.

Now as an example, but not limiting one, refer to FIGS. 5-7. In thisembodiment the profile 8 and the first body 6 comprise one a firstprotrusion 93 and the other a first groove 94 in which the firstprotrusion 93 is inserted and along which the first protrusion 93 mayslide. This means that: the first protrusion 93 is part of the profile 8and the first groove 94 is part of the first body 6; or vice versa thefirst protrusion 93 is part of the first body 6 and the first groove 94is part of the profile 8.

The first protrusion 93 could also rotate inside the first groove 94 topermit the profile 8 to be tipped. In this way the first protrusion 93advantageously defines a pivot. Preferably this pivot is cylindricallyshaped. The first groove 94 extends orthogonally to a rotation axisdefined from the pivot.

When the first and the second connector 91, 92 are set in the secondoperating mode the first portion 81 of the profile 8 can be moved out ofa lying plane of the first panel 4, so as not to intersect the profile 8with said plane (this lying plane is the plane where is the first panel4 when the first and the second connector 91, 92 are in said firstoperating mode). In this way, the profile 8 can remain connected to thedoor 8, but at the same time does not prevent with his presence theremoval of the first panel 4.

The first groove 94 advantageously extends parallel to a plane that isperpendicular to said lying plane of the first sheet 4.

The first groove 94 comprises a first and a second parts 941, 942; insaid closed position of the door 3 said first part extending from a highpoint to a low point and said second part 942 being transverse to saidfirst part 941. In particular, the second part 942 in the closedposition of the door 3, connects to the lower area of the first part941. Conveniently, the first and the second parts 941, 942 extend in “L”shape. In the embodiment the first and second parts are joined up(preferably by means of an arc of a circle) and when the profile 8 is inthe first position, the first protrusion 93 lies in the first part 941.Profile 8 is removed from the first panel 4 by moving the firstprotrusion 93 first along the first part 941 and subsequently by movingthe first protrusion 93 along the second part 942.

Profile 8 and the second body 7 comprise one a second protrusion and theother a second groove in which the second protrusion is inserted andalong which the second protrusion can slide. Preferably the first andthe second protrusions are symmetrical to an imaginary symmetricalplane.

Conveniently, the first and the second grooves are symmetrical to thesame plane of symmetry. What has been described with reference to theinteraction between the first protrusion 93 and the first groove 94 maybe repeated for the interaction between the second protrusion and thesecond groove.

The door 3 therefore comprises means for connecting the profile 8 to thefirst and/or to the second body 6, 7. The connection means are notremovable connection means. These connection means comprise thereforethe first protrusion 93 and the first groove 94. Conveniently theconnection means also comprise the second protrusion and the secondgroove.

Conveniently, the first protrusion 93 extends from the first body 6. Inaddition to the first portion 81 described above, the profile 8comprises a second portion 82 which is transverse to the first portion81 and that at least in the first position of the profile 8 overlaps thefirst body 6; the first groove 94 is formed in said second portion 82.

Additionally, a method for removing the first panel 4 from an ovenhaving one or more of the features described above is also disclosed.This method for removing comprises the steps of: releasing theconnection means 9 of the push-push type; sliding the first panel 4 fromremaining parts of the door 3.

The step of releasing the connection means 9 of the push-push typecomprises the steps of: applying a disconnection pressure, which causesthe profile 8 to move toward the first panel 4 of the door 3; releasingprofile 8 causing the movement of the profile 8 from the first panel 4.

More in particular, object of the present invention is a method forremoving and/or repositioning the first panel 4 of an oven having one ormore of the characteristics described above. In particular the removalof the first panel 4 comprises the steps of: I) removing the profile 8from said first position by releasing the connection means 9 of thepush-push type; II) sliding the first panel 4 from remaining parts ofthe door 3.

The step of releasing the connection means 9 of the push-push typecomprises the steps of applying a disconnection pressure, which causesthe profile 8 to move toward the first panel 4; the movement of theprofile 8 toward the first panel 4 pushing the first element 911 and thefirst component 921 respectively on the second element 912 and on thesecond component 922. This push causes an opening of a first and asecond pair of jaws belonging respectively to the second element 912 andthe second component 922. As indicated previously, the first element 911and the first component 921 are male elements which perform the actionof pushing respectively in correspondence of the junction region of theclamps of the second element 912 and the second component 922 (thesejaws define then female elements with which the first element 911 andthe first component 921 interact). The first and second pair of jaws insaid first position performs a retaining action respectively on thefirst element 911 and on the first component 921.

The opening of the first pair of jaws permits then the first element 911to be freed from the grip of the second element 912. Similarly theopening of the second pair of jaws enables the first component 921 to befreed from the grip of the second component 922.

Although previously it has been made reference to a situation in whichthey interact both the first and the second connector 91, 92, the lattercould also be absent. For example in the embodiment of FIGS. 5-7 theremoval of the first panel 4 also comprises the step of moving theprofile 8 by sliding the first protrusion 93 in a first time along thefirst portion 941 of the first groove and subsequently along the secondportion 942 of the first groove 94. The method also comprises the stepof tipping of the profile 8 by rotating it around the said pivot definedby the first protrusion 93. This tipping step typically occurs when thefirst protrusion 93 is in the second part 942.

Conveniently, the tipping step of the profile 8 allows to place theprofile 8 opposite to the second panel 5 (in a position out of the spacethat does not block the removal of the first panel). The moving of thefirst protrusion 93 along the first part 941 of the first groove 94allows the movement of the profile 8, which is to disengage from thefirst panel 4. The moving of the first protrusion 93 along the secondpart 942 of the first groove 94 allows to remove the profile 8 by thesecond panel 5 so as to allow the subsequent tipping of profile 8(alternatively, the second panel 5 would find just the profile 8,preventing the positioning of the profile 8 opposite to the second panel5). As already mentioned above, what has been described with referenceto the movement of the first protrusion 93 along the first groove 94 maybe repeated for the movement of the second protrusion along the secondgroove (this allows to move the profile 8 while maintainingsubstantially horizontal its preponderant development direction).

The repositioning of the first sheet 4 includes the steps of: I)applying the first panel 4 to the remaining parts of said door 3 byinserting it in support means obtained in said door 3; II) positioningthe profile 8 in said first position by connecting push-push connectionmeans 9.

The step of positioning the profile 8 in said first position byconnecting push-push connection means 9 comprises the steps of:positioning said first and said second element 911, 912 of the firstconnector 91 opposite each other; positioning said first and said secondcomponent 921, 922 of the second connector 92 opposite each other;applying a connection pressure which pushes said profile 8 toward thefirst panel 4 of the door 3; in this case, the connection pressure anddisconnection pressure are oriented along the same direction relative tothe door 3.

The movement of the profile 8 toward the first panel 4 determines apushing of the first element 911 and the first component 921respectively on the second element 912 and the second component 922.This pushing causes a movement of the first and second pair of jaws;during this movement, the first and the second pair of jaws are incontact with the matching parts that determine their closing; in thisway, the first and the second pair of jaws grip respectively the firstand second element 911, 912.

The present invention allows to achieve multiple advantages. First ofall, it allows a fast passage of profile 8 from said first to saidsecond position and vice versa. In addition, the profile 8 is easilyaccessible to the user and this allows to make extremely convenient thecleaning operation of the door of the oven. In addition, a furtherimportant advantage is related to the fact that the removal andinstallation of the first panel 4 may take place without the aid oftools.

The invention thus conceived is susceptible to numerous modificationsand variations, all of which are within the scope of the invention thatcharacterized it. In addition, all the details can be replaced by otherelements technically equivalent, in practice, all the used materials, aswell as the dimensions, may be any, depending on requirements.
